Fast score test with global null estimation regardless of missing genotypes. [PDF]
PLoS ONE, 2018 In genome-wide association studies (GWASs) for binary traits (or case-control samples) in the presence of covariates to be adjusted for, researchers often use a logistic regression model to test variants for disease association.

Generalised Score and Wald Tests [PDF]
Advances in Decision Sciences, 2010 The generalised score and Wald tests are described and related to their nongeneralised versions. Two interesting applications are discussed. In the first a new test for the Behrens-Fisher problem is derived. The second is testing homogeneity of variances from multiple univariate normal populations.

Type I error control for cluster randomized trials under varying small sample structures
BMC Medical Research Methodology, 2021 Background Linear mixed models (LMM) are a common approach to analyzing data from cluster randomized trials (CRTs). Inference on parameters can be performed via Wald tests or likelihood ratio tests (LRT), but both approaches may give incorrect Type I ...

On testing proportional odds assumptions for proportional odds models
General Psychiatry, 2023 Proportional odds models are commonly used to model ordinal responses, but the proportional odds assumption may not hold in practice, leading to biased inference.

Asymptotic Sample Size for Common Test of Relative Risk Ratios in Stratified Bilateral Data
Mathematics, 2023 In medical clinical studies, various tests usually relate to the sample size. This paper proposes several methods to calculate sample sizes for a common test of relative risk ratios in stratified bilateral data.

Robust Test Statistics Based on Restricted Minimum Rényi’s Pseudodistance Estimators
Entropy, 2022 The Rao’s score, Wald and likelihood ratio tests are the most common procedures for testing hypotheses in parametric models. None of the three test statistics is uniformly superior to the other two in relation with the power function, and moreover, they ...

Testing for changes in forecasting performance [PDF]
, 2019 We consider the issue of forecast failure (or breakdown) and propose methods to assess retrospectively whether a given forecasting model provides forecasts which show evidence of changes with respect to some loss function.
